Abstract
An integrated circuit stores analog or digital information, or both, in memory cells (416). The memory cells provide analog or multilevel storage. Analog information is provided through an analog signal input (405), and digital information is provided through a digital signal input (407). A scheme for storing digital information is consistent with the scheme used to store analog information. Data is retrieved from the memory cells, and output to the analog or digital signal output (454, 463) depending on the type of data. A digital reference generator reference generator (425) generates various analog equivalent voltages for the digital signal input.
